Module 9
The module defines the switch-on and switch-off positions of the laser, and thus deter-
mines the length of the scan beam. The position is set as a percentage of the beam dura-
tion. The beam duration corresponds to the reading field width, which is specified in the
diagrams in chapter "Optics variants and reading fields" on page 22.
